I uninstalled Threat Fire and now the computer is stable, if laggy, with Verifier running, at least for several hours.
A few hours after turning off Verifier, while I had several things open and was talking on the phone, another BSOD appeared. I have the image, but there is no dump file because it got stuck, I took an photo with my phone.
If ThreatFire isn't completely stable, I'm not that worried. I'm worried about what is causing these BSODs and it doesn't seem to be driver related.
